This is a great looking system! As others have commented, I love the simplicity, and especially the focus (all American-made components). My focus is largely older (sometimes vintage and considered classic) that I can refurbish and/or tweak.
Have you tried using your Emotiva DAC with the Sonos? While the onboard DAC is solid (I think it's a CS, but can't remember), many people have gotten better results using an outboard DAC.
